摘要： A CT system includes a generator configured to energize an x-ray source to a first kilovoltage (kVp) and to a second kVp, and a computer that is programmed to acquire a first view dataset with the x-ray source energized to the first kVp and a second view dataset with the x-ray source energized to the second kVp, generate a base correction image using the first view dataset and the second view dataset, and reconstruct a pair of base material images from the first view dataset and from the second view dataset. The computer is also programmed to estimate artifact correlation in the pair of base material images using the base correction image, generate a pair of final base material images and a final monochromatic image, and correct one of the pair of final base material images and the final monochromatic image at a keV value using the estimated artifact correlation.

摘要： An imaging system includes a rotatable gantry having an opening therein to receive a subject to be scanned and configured to rotate about a central axis in a rotation direction. The imaging system also includes a first x-ray source coupled to the rotatable gantry at a first position, wherein the first position is offset from the central axis of the rotatable gantry by a first distance. Further, the imaging system includes a second x-ray source coupled to the rotatable gantry at a second position, wherein the second position is offset from the central axis of the rotatable gantry by a second distance, wherein the second position is offset from the first position in a direction coincident with the rotation direction, and wherein the second position is offset from the first position in a direction parallel to the central axis.

摘要： A champagne type base for a molded polymeric container has an annular step immediately inside an annular contact ring. A push-up area is a central portion of the base immediately surrounding the container longitudinal axis. A transition region between the push-up area and the annular step provides for outstanding base stabilization. The transition region includes an upwardly arching surface extending between the annular step and the push-up area with a plurality of integrally molded, spaced apart, radially extending and downwardly projecting hollow ribs. Each of the ribs has a lower curved surface extending substantially continuously from the push-up area to the inner margin of the annular step.
